Title: Transmission data processing device
IPC: G06F3/02
Filed: 1975-06-03
Abstract: 1516672 Data transmission CASIO COMPUTER CO Ltd 3 June 1975 [7 June 1974] 23938/75 Heading H4P [Also in Division G4] A transmission data processing device handles m-bit and n-bit characters (m greater than n). in part under control of an m-bit-designating n-bit code. In a computer, a keyboard supplies a series of parallel-by-bit characters to serializing gates, each character being of 4 bits (numeral or function) or 8 bits (letter). The keyboard output also goes to an OR gate (to detect each character), an AND gate responsive to two bits to detect a "word begin/end" function character, and an OR gate responsive to the 5th-8th bits to detect an 8-bit character, these gates controlling a bit-number selector which, together with a 4-output timing pulse generator. controls the serializing gates so that 8 bit times are allotted to each character starting with the first 8- bit character in a word until the next "word begin/end" function character is reached, other characters being allotted 4 bit times each. In addition, a 4-bit "letters" function character is inserted into the serial bit stream from the serializing gates by logic under the control of the bit-number selector and timing pulse generator, just prior to the first 8-bit character in the word. The serial bit stream is stored in a memory (magnetic drum, disc or tape). The memory output is supplied, serial-by-bit, to a shift register, gates responding to this to recognize the "word begin/  end" and "letters" function character to control logic to pass each character, parallel-by-bit, from the first part or the whole of the shift register (depending on whether the character is 4 or 8 bits) to a register controlling a printer.

Title: Process of and apparatus for the pyrolytic conversion and coking of mixtures of finely divided solid carbonaceous material and hydrocarbon oil
IPC: C10B55/02
Filed: 1933-08-29
Abstract: <PICT:0409969/III/1> Mixtures of finely-divided solid carbonaceous materials and hydrocarbon oil are cracked and coked by subjecting the mixture to conversion temperatures and introducing the heated products into a coking zone where they are separated into residues and vapours which are fractionated to produce a light distillate while the residues are coked in thin layers on a highly heated surface. Alternatively part or all of the mixture may be introduced directly into the coking zone, and a fraction obtained therefrom is subjected to conversion at high temperatures and then introduced into the coking zone.  Crude oil stock is delivered by a pump 3 through a pipe 4 into a mixing chamber 6 where it is mixed with finely-divided coal supplied from a hopper 7.  The mixture is pumped through a conversion coil 14 heated to 450--480 DEG  C., or directly through pipes 18, 21, 21<1>, 21<11>, to coking ovens 23, 23<1>, 23<11>, used in series where the products separate into vapours and residues and the latter are coked in layers on floors 24 of refractory material, e.g. silicon carbide, aluminium oxide or silicate.  The vapours are withdrawn to a fractionating tower 29 from which a light final distillate passes off through a pipe 30 and is condensed in a coil 32, and separated from gases in a receiver 35. Part of the distillates may be returned as reflux to the tower 29. The high boiling reflux collecting at the bottom of the tower 29 is removed through a line 45 and to a discharge pipe 49 or returned to the system through a pipe 51 (a) to the mixing tank 6 through a pipe 70, (b) to the coil 14 through a pipe 54 or (c) through a pipe 52 to the coking chambers.  An intermediate fraction is withdrawn from the tower 29 through a pipe 57 to a column 59 where it may be reboiled by steam introduced through a line 60, the vapours evolved being returned to the column 29.  The unvaporized fraction is returned through pipes 67, 70 to the system and may be introduced through the line 70 into the tank 6, or through a pipe 71 into the coil 14.  When this fraction alone is passed through the coil 14 a higher conversion temperature of 450--500 DEG  C. is maintained in this coil.  The coking ovens and the fractionating towers are preferably maintained under atmospheric or sub-atmospheric pressure.

Title: Improvements in and relating to thread guides for winding machines
IPC: B65H54/36
Filed: 1934-08-27
Abstract: 432,325. Thread - winding machines. LIEBERKNECHT GES., K., Oberlungwitz, Saxony, Germany. Aug. 27, 1934, No. 24689. Convention date, March 19. [Class 120 (ii)] The traversing thread guide of a machine for winding bobbins in conical form is advanced at the end of each traverse by an actuating device, positively driven from the lifting mechanism independently of the thread and normally held in the inoperative position by a detecting device which is engaged and tripped by the thread when winding is taking place at the maximum diameter of the bobbin. As shown, the guide 18 is carried by a plate 14 mounted in a vertical screwed shaft 2 journaled in the lifter rail 1 and the plate is guided against rotation by a parallel shaft 3. The shaft 2 carries a ratchet wheel 6 engaged by a pawl 5 on a bail 4 of the thread-guide actuating device pivoted at its ends to the shaft 2 and engaged by pins 9 on the arm 7 of a bell-crank lever pivoted on the lifter rail and carrying a counterbalance weight 13 at the end of its other arm 8. At the start of the winding the bail 4 is locked by a pawl 23 secured to a pin 20 pivoted in the plate 14 and carrying a lever 21 of the detecting device which is controlled by a light spring 21<a> to hold the pawl in the locking position ; a roller 22 is mounted on the free end of the lever 21 and when the thread 17 is being wound on the maximum diameter of the bobbin it contacts with the roller 22 and moves the lever 21 against the action of the spring 21<a> to displace the pawl 23 from engagement with the bail 4 which is moved past the pawl by the weighted lever 7, 8, a pin 10 on the arm 7 of the lever moving into the slot of a control plate 11 fixed to the machine frame. As the lifter rail rises the pin 10 moves along the face 24 of the plate 11 and pivots the lever 7, 8 to move the bail 4 and pawl 5 to rotate the ratchet 6 and advance the thread guide along the shafts 2, 3. As soon as the thread leaves the roller 22 the pawl 23 is moved by the spring 21<a> to lock the bail 4, and as the rail 1 descends the pin 10 moves past the outside edge of a retaining element 26 on the plate 11 and moves the bail slightly out of engagement with the detecting device so that the latter can move freely when the thread again contacts with the roller 22.
